After I sent the message below, I looked in the "Forms" view, and there was no Sch 8812 in my return. In the "Step-by-Step" view I went to the "Child and other Dependent Tax Credit" (under the Deductions and Credits), and filled out the fields and, as expected, got no credit.
Then I did the error check again. I don't know why, but the errors went away (not that I'm complaining). If this is a bug in TurboTax, you should fix it.
